Kellock told Press Association Sport: "There's a lot of areas that need to go right for us, but if they go right we've got an opportunity. We need to control the ball, we need to stop their counter-attack, we need to stop the set-piece."

He added: "It's something we've not done in a game so far. We've done some things extremely well, but there's always been two or three areas that we need to tighten up on.

"That's what England have been very strong at. They have got everything working and going in the same direction."

Scotland entered the competition with five wins from six Tests and, having beaten Australia and world champions South Africa in head coach Andy Robinson's 18-month reign, retain the belief they can defeat anyone.

Kellock added: "There was a large degree of expectation before the championship which was well merited based on the results we've had over the last couple of years.

"So far it's not been anywhere near where we wanted it to be or where anybody else wanted it to be.
